This mod adds 90 new food items, trying to keep things canon friendly. You can find them as randomized food loot, or buy them in any Inn/Tavern from the base game. I plan to expand the mod to include Tamriel Rebuilt content and Inns on the Mainland later on, but it sticks to vanilla now. Regardless, any food seller, both from the base game and TR has a chance to sell some random basic food items along normal ingredients.

Each Inn has a different pool of random regional dishes they serve. Telvannis serve Telvanni themed food, Redoran Redoran themed food, Imperial settlements have more globalist vibes etc. There is even a secret spot where you can get Sixth House themed food!

Food and dishes give you different types of bonuses. The idea here was to get very small buffs to more physical aspects of your character, but long-lasting ones, with durations up to 30min (although food usually works for 10-20 minutes). There are no hard categories for food, but they lean from small snacks, through dinner-like dishes, to huge gourment feasts. The more caloric the food, the longer duration of it's effects, but it also burdens your stomach.

The main idea behind my mod, was to add more clutter to collect, place in your in-game house, and make things varied in general. I have several ideas for "Expanded Loot" mods aiming into that. Morrowind is a perfect game as it is, but you can always can have MORE STUFF TO FIND AND COLLECT. It started to be somewhat important to me to midway, to simply have some way of interacting with those items, so I started to plan out buffs particular food could give, so using those items at all would still be a viable choice. 

In making the mod, I've used vanilla textures and models, some textures and models I've made myself, and some stuff from Tamriel Data (kwama meat model and texture and deshaan bread texture, I needed that for a roast and sandwiches lol).

I plan to upgrade the mod later on, to actually place the food in the world in every Inn both in Vvardenfell and on TR Mainland, but it's time consuming so I'm posting what I have for now.

Big thanks to Melchior Dahrk for splitting the mod into .esm and .esp and ordering folder structure.
